Abstract

The invention discloses a dawsonite and zinc tetrafluoroborate compounded flame retardant EVA electric cable material and a preparation method thereof, wherein the dawsonite and zinc tetrafluoroborate compounded flame retardant EVA electric cable material is prepared from the following raw materials by weight: 57-72 parts of an EVA resin, 14-18 parts of chloro-methoxy fat diethylene glycol dinitrate, 29-43 parts of polyphenylene sulfide, 25-40 parts of bisphenol A polysulfone, 10-15 parts of zirconyl chloride, 5-10 parts of pentachlorobibenzene, 17-23 parts of diatomaceous earth, 10-15 parts of brominated paraffin, 20-25 parts of graphite tailings, 12-18 parts of dawsonite, 10-15 parts of zinc tetrafluoroborate, 3-4 parts of barium stearate, 2-3 parts of cadmium stearate, 8-16 parts of zircon powder, and 15-20 parts of fixing sulfur ash. The dawsonite and zinc tetrafluoroborate compounded flame retardant EVA electric cable material of the present invention has advantages of high mechanical strength, good heat aging resistance, good flame retardant effect, good smoke suppression performance and no toxicity, and is suitable for all kinds of electric cables.

Description

technical field [0001] The invention relates to a dawsonite compound zinc fluoroborate flame-retardant EVA cable material and a preparation method thereof, belonging to the technical field of cable material manufacturing. Background technique [0002] Ethylene-vinyl acetate copolymer, English abbreviation: EVA, has a wide range of applications in the wire and cable industry because of its good physical and mechanical properties and processability, especially its high fillability. In recent years, with the rapid development of the wire and cable manufacturing industry, the requirements for the flame retardancy of EVA cable materials are getting higher and higher, and the flame retardancy of traditional EVA cable materials is increasingly unable to meet the needs of the market. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a dawsonite compound zinc flu...
